21 Speeds Aviation Grade Aluminum Alloy Frame Road Bike Shimano Shifter System

Description:

Assembly and Tuning Required

The pedal threads differ between the left and right side. L/R marks are embossed on the spindle of each pedal, ensure they are assembled on the correct side (when riding the bike the left pedal should be on your left hand side, right pedal on right hand side). The right pedal has a right-hand thread (removes counterclockwise, installs clockwise). The left pedal has a left-hand thread (removes clockwise, installs counterclockwise).

Thread both pedals into the crank arms as far as you can by hand, then fully tighten them with the wrench. If the pedals are not fully tightened, they may become loose and damage the threads, we will not be responsible for such damages.

For safety reasons, tires are not fully inflated before shipping. Before your first ride, it's suggested that you inflate the tires properly.
